This study intends to suggest the cooperative, win-win collaboration, as methods for settling disputes with the existing self-employed people over back-street business areas and disputes and conflicts between a franchiser and franchisees. In addition, it intends to analyze the Dunkin' Donuts purchasing cooperative in the US, where the franchising industry has been well developed; and to find the implications of cooperation strategies between Dunkin' Donuts and its franchisees that may be helpful for the South Korea's franchising industry. This study tries to discover a new model of the Korean-style franchise cooperative out of the basic principles and practice guidelines of cooperatives ranging from an early American franchise cooperative in 1955 to ARCOP, KFC, and Dunkin' Doughnuts in the late 1970s. Further, it looks into successful programs of a purchasing cooperative at Dunkin' Donuts such as TDP (Total Distribution Program), SFP (Shortening Futures Program) and DCP (Distribution Commitment Program). The case of the US Dunkin' Donuts, which operates the purchasing cooperative, suggests the following for the improvement of franchisees' profitability. First, relations of cooperation rather than of power are necessary between a franchiser and franchisees. Second, mutual solidarity of franchisees is necessary. Third, problems proper to the Korean franchise system should be improved. Fourth, an entrepreneurial spirit of going together rather than going fast is required. Fifth, complete satisfaction management is required. Considering different system environments between the two countries such as quantitative expansion within a short franchising history of 30 years or so and franchise profit models, there is a limit to generalizing down to a successful model of the win-win partnership cooperative. It is hoped that the sustainable management of the domestic franchising industry will be promoted in the future through the in-depth analysis of successful cooperatives.

The behavior of a three-dimensional pure rectangular water jet with aspect ratio of 10 was experimentally investigated based on the results of the mean velocity field obtained by PIV. The saddle back distribution was observed in the lateral distribution along the major axis. The theoretical centerline velocity equation derived from the point source concept using the spreading rate for the axisymmetric jet was in good agreement with the measured centerline velocity and gave the division of the potential core region, two-dimensional region, and axisymmetric region. The range of the two-dimensional region divided by the criterion of the theoretical centerline velocity decay for the aspect ratio of 10 was observed to be smaller than that of the transition region. The applicability of the two-dimensional model to the behavior of the rectangular jet with low aspect ratio or the wastewater discharged from a multiport diffuser in the deep water of real ocean may result in significant error in the transition and axisymmetric regions after the two-dimensional region. In the two-dimensional region, the Gaussian constant tended to be conserved, and the spreading rate slightly decreased at the end of the two-dimensional region. The normalized turbulent intensity along the centerline of the jet initially abruptly increased and showed relatively higher intensity for higher Reynolds number.

Assessing seasonality of precipitation is necessarily required to establish future plans and policies for water resources management. In this regard, a main objective of the study is to introduce an effective approach for assessing the seasonality of the precipitation and evaluate the seasonality through the proposed one. We have used circular statistics to characterize the seasonality on the precipitation in Korea. The circular statistics allow us to effectively assess changes in timing of the seasonality in detail. It was found that peak time on monthly rainfall occurred between end of June and early July in southern coastal area while the timing was delayed in northern part of Korea because of monsoon moving in from south to north. In case of annual daily peak precipitation, spatio-temporal variation of the peak time was increased. It is mainly because of geophysical effects, frequency and paths of typhoons. Finally, temporal variations on the timing of the peak seasons were evaluated through circular statistics by 30-year moving average data. The peak season in the Northen part of Korea (e.g. Seoul and Gangrung) has been moved back from early July to end of July while the peak season has been moved up from middle of July to early July in the Southern part of Korea (e.g. Busan and Mokpo). It seems that changes in seasonality are mostly modulated by variability in the east-asia monsoon system.
Shopping is considered a 'must-do' activity for most people on travel. One of the major parts of tourist shopping is the purchasing of souvenirs. Souvenirs are universally associated with tourism as a commercially produced and purchased object to remind the purchaser of the experience. Recently, Korea becomes one of the most popular destinations that many Asian tourists like to visit. Among those Asian tourists, the number of Thai tourists bound for Korea shows an incredible rapid growth. Thai people pick Korea and Seoul as their favorite country and city to visit for three consecutive years since 2009. One of the major reasons why Thais are choosing to tour Korea is the enthusiasm for Korean pop culture. That is, 'Hallyu' has influenced Thais' decision to visit Korea and purchase Korean products. The primary objective of the current research is to explore the shopping experiences of Thai tourists, specifically their souvenir shopping. It adopts a reflexive interpretive approach to bring light to the various meanings Thai tourists attach to the souvenirs they purchase in Korea. In order to accomplish the objective, the individual interviews were conducted. A total of 12 Thais who have experienced traveling in Korea participated in the study. Four themes were identified through interview text analysis. First, the research participants almost always purchase souvenirs in Korea because the souvenirs represent their identities as tourists. Especially, they purchase the souvenirs as gifts for others, including family members, friends, and colleagues. The souvenirs as gifts show love and thanks to others, and they cement the social relationship. However, purchasing souvenirs for others is more like the moral obligations which evoke the psychological stress. Secondly, the research participants feel closer to Korea while shopping souvenirs around. Thirdly, they obtain imaginative experiences and pleasure through souvenirs related to the Korean pop culture. Souvenirs provide them to visually extraordinary experiences. Lastly, souvenirs purchased in Korea act as visible status marker when they go back to Thailand. They show the socioeconomic status and lifestyles. Tourists themselves and others place special value to souvenirs that were purchased out of Thailand. The findings of this study are of both academic and practical importance. Souvenirs are among the most pervasive elements of the travel experience. However, souvenir shopping is the complicated consumer behavior within tourism both from business and social science perspectives. Along the same line, it needs strategic approaches in order to maximize the economy effects. It concludes by suggesting how further research could offer unique insights into how the souvenirs are positioned both in the context of tourism academics and industry.

Orostachys species grow from anywhere in Korea. This variety, which lives in the harsh areas of the beach and mountains, is known to have as much change as it was isolated. It has been used as a medicine for a long time, and now the flower is beautiful and has been developed for horticulture. As a result of morphological characteristics and component analysis of three Orostachys species, the following results were obtained. 1. Orostachys species showed two types of leaves according to the growing environment. O. japonica (Maxim.) A. Berger and O. minuta (Kom.) A. Berger were lanceolate, and O. chongsunensis Y. N. Lee was obovate. 2. The leaves were all green. However, some of the O. japonica (Maxim.) A. Berger had white powder. Some of the O. minuta (Kom.) A. Berger was green with red spots on the back. O. chongsunensis Y. N. Lee showed strong gray before flowering but weak green when flowering. 3. The thorns of the leaves were O. japonica (Maxim.) A. Berger and O. minuta (Kom.), but O. chongsunensis Y. N. Lee was not. 4. Whether it was a leaf dot or not, there were dots in O. japonica (Maxim.) A. Berger and there were dots on the O. minuta (Kom.) and the O. chongsunensis Y. N. Lee. 5. The flowers were all white, and the stamens were red in O. japonica (Maxim.) A. Berger and O. minuta (Kom.) A. Berger and white in O. chongsunensis Y. N. Lee. 6. It was confirmed that the ingredients in Orostachys species contained kaempferol, quercetin, flavonoid etc., which have high antioxidant activity.
Under the Trump administration, the U.S. has made clear that "China is America's strategic competitor, revisionist power and a major challenge to America's prosperity and security." The Biden administration has largely inherited this perception of China. China has also responded without backing down. Therefore, the U.S.-China strategic competition has become the most important background factor in the international system and has a great impact on the security situation in Northeast Asia. Nevertheless, if you look at the recent process of establishing trilateral security cooperation among ROK, the U.S. and Japan, we can find that ROK's foreign strategy adjustment has played a key role. This is because establishing trilateral security cooperation among ROK, the U.S. and Japan depends on improving ROK-Japan relations. And the Yoon Suk Yeol government is pushing for rapid improvement in ROK-Japan relations regardless of domestic political constraints. The trilateral summit at Camp David laid the groundwork for future cooperation among ROK, the U.S. and Japan in security and other broader areas. China is strongly dissatisfied with the formation of trilateral security cooperation among ROK, the U.S. and Japan. However, this paper argues that although ROK agrees to form trilateral security cooperation with the U.S. and Japan, ROK's strategic objectives are not exactly the same as those of the U.S. and Japan. For example, looking back at the development of the U.S.-Japan alliance after the end of the Cold War, both the U.S. and Japan share similar views and perceptions of China's rise. The real goal of the strengthening of the U.S.-Japan alliance in recent years is also how to cope with China's rise. On the other hand, ROK's previous administrations have been negative about trilateral security cooperation with the U.S. and Japan. This is because ROK's main strategic goal is to reduce or eliminate threats from DPRK rather than respond to China. Faced with increasing DPRK's provocations and threats, more than half of South Koreans are in favor of reinforcing trilateral security cooperation with the U.S. and Japan to contain or mitigate threats from DPRK. As a result, if North Korea's nuclear and missile threats to ROK continue, then ROK's foreign strategy is likely to be to strengthen trilateral security cooperation between the U.S. and Japan to ensure its own safety and survival. If China wants to reduce the strategic pressure from the trilateral security cooperation among ROK, the U.S. and Japan, the best way is to reduce DPRK's provocations and threats to ROK and play a more substantive role in getting DPRK to give up its nuclear program.
In this paper, we propose a novel algorithm for predicting the number of apples on an apple tree using a deep learning-based object detection model and a polynomial regression model. Measuring the number of apples on an apple tree can be used to predict apple yield and to assess losses for determining agricultural disaster insurance payouts. To measure apple fruit load, we photographed the front and back sides of apple trees. We manually labeled the apples in the captured images to construct a dataset, which was then used to train a one-stage object detection CNN model. However, when apples on an apple tree are obscured by leaves, branches, or other parts of the tree, they may not be captured in images. Consequently, it becomes difficult for image recognition-based deep learning models to detect or infer the presence of these apples. To address this issue, we propose a two-stage inference process. In the first stage, we utilize an image-based deep learning model to count the number of apples in photos taken from both sides of the apple tree. In the second stage, we conduct a polynomial regression analysis, using the total apple count from the deep learning model as the independent variable, and the actual number of apples manually counted during an on-site visit to the orchard as the dependent variable. The performance evaluation of the two-stage inference system proposed in this paper showed an average accuracy of 90.98% in counting the number of apples on each apple tree. Therefore, the proposed method can significantly reduce the time and cost associated with manually counting apples. Furthermore, this approach has the potential to be widely adopted as a new foundational technology for fruit load estimation in related fields using deep learning.
With the emergence of new digital technologies into a supply chain, it is essential for companies to incorporate these technologies in managing their supply chains. However, various challenges have been identified in digital supply chain management, especially when it comes to its assessment. There are no universally agreed measurements for the performance of digital supply chain management within the research community so far. This paper explores an option of using user experience as one of possible measurements. Therefore, three different focus-group discussions were held and later analyzed with a qualitative content analysis. The subscription-based video on demand service, Netflix was used as an example in those discussions. Due to the fact that Netflix provides a digital product as a streamline service, user experience is critical for the company. Especially, user experience with a recommender system and related privacy issues have become significant for a company to retain existing customers and attract new customers in many fields. Since the recommender system and related privacy issues are parts of a digital supply chain, user experience can be one of appropriate measurements for digital supply chain management. This study opens a new perspective for research on performance measurements of digital supply chain management.

Primary central nervous system lymphoma is a rare form of extranodal non-Hodgkin lymphoma, and primary T-cell lymphoma of the cauda equina is extremely rare. We describe a case involving a 56-year-old female who presented with low back pain and radiating leg pain for 4 months. MRI of the lumbar spine revealed an elongated, multinodular intradural lesion of approximately 10 cm from the L4 body to the S2 body level with iso-signal intensity on T1-weighted imaging, heterogeneous iso- and high-signal intensity on T2-weighted imaging, and a heterogeneous intense enhancement on gadolinium contrast-enhanced T1-weighted imaging. A peripheral T-cell lymphoma of the cauda equina was diagnosed on the basis of immunohistochemical and T-cell receptor gamma gene rearrangement analysis after intradural biopsy of the mass.

Objectives: The purpose of this study is to analysis the clinical study trends on Korean Medicine treatment for Bell's palsy during pregnancy. Methods: Key words such as 'facial palsy', 'Bell's palsy, 'Korean medicine', 'herbal medicine', 'acupuncture', 'pregnancy' were searched through the 'RISS', 'OASIS', 'KISS', 'PubMed' and 'CNKI' databases. Results: Ten clinical studies with 107 patients were selected, and 1 randomized controlled trial and 9 case reports were included as the target studies. In the 9 case reports, the gestational age at the onset of facial palsy was most common in the third trimester (29-42 weeks) in 38 cases (56.7%). The most commonly used Korean medicine interventions were acupuncture, with the most frequently used acupoints being ST4, ST2, ST6, BL2, TE23, LI20, GB1, GB14, SI18, and CV24. The herbal medicine treatment most commonly utilized was Geumgwedanggwi-san (金匱當歸散), which is related to the principles of clearing heat, nourishing blood, and stabilizing the fetus (淸熱養血安胎). Among the 65 participants evaluated using the House-Brackmann facial nerve grading system, 81.5% showed complete recovery to grade 1, while 6% remained at grade 4 with no effect, indicating the efficacy of Korean medicine treatment for facial palsy during pregnancy. All the selected studies reported no abnormalities in the mothers or fetal growth, and all participants who had the reported delivery had full-term childbirth. Conclusions: The effect on Korean Medicine treatment for Bell's palsy during pregnancy had mostly positive results. However, further large, well-designed clinical trials are needed to establish the foundation of Korean Medicine treatment for Bell's palsy during pregnancy.
